Stainless steel microwires generally refer to 304, 304L, 305, 316, 316L and other materials which are drawn into soft industrial metal filaments with a diameter of less than 0.1 mm and can be wound. The stainless steel microwires produced by our factory are mainly of 316L, which are drawn from Japan’s SUS Xinri stainless steel imported raw materials. 316L stainless steel is also called titanium steel, fine steel, titanium steel, and its composition ratio is: 022Cr17Ni14Mo2. 316L stainless steel has good appearance and gloss. The addition of Mo greatly improves the corrosion resistance of the material, especially the superior pitting corrosion resistance. In addition, 316L stainless steel has excellent strength in high temperature environments, good work hardening, weak magnetic after processing, and non-magnetic in the solid solution state. These high-quality features are not available in other grades of stainless steel such as 316 and 304.
The stress state of stainless steel microwire drawing is the three-dimensional principal stress state of two-way compressive stress and one-way tensile stress. Compared with the principal stress state of compressive stress in all three directions, the drawn stainless steel wire is easier to reach the state of plastic deformation. The deformation state of drawing is a three-way main deformation state of two-way compression deformation and one tensile deformation. This state is not good for the plasticity of metal materials, and it is easier to produce and expose surface defects. The amount of pass deformation in the drawing process of stainless steel microwires is limited by its safety factor. Smaller pass deformations result in more drawing passes. Therefore, multiple passes of continuous high-speed drawing are often used in the production of stainless steel microwires. At present, the smallest diameter of stainless steel microwires can reach 0.5 microns, the longest can reach tens of meters or even hundreds of meters, the elongation rate is greater than 1%, and the fiber strength can reach 1200-1800Mpa.
In the design of high-class clothing, the application of stainless steel microwire is considered the finishing touch. The lively color, bright luster, anti-radiation and anti-static health concepts are destined to be the darling of the future fashion market. Stainless steel micro-filament textile fabrics can be used in the production of high-end clothing for men and women, highlighting the elegant, luxurious, romantic temperament and high-end taste of the wearer, but also has other more extensive uses. Pure stainless steel micro-filament textiles can be used to make pillow-type sealing belts, dust bags, hot workpiece conveyor belts, heat insulation curtains, heat-resistant cushions, etc.; stainless steel micro-filament blended textiles can be used to make high-voltage shielding clothing, anti-static work clothes, and anti-static Carpets, electromagnetic wave protective clothing and protective covers, maternity clothing, medical surgical clothing, etc. Stainless steel microwire textiles can also be used to make fake military targets and radar targets, which can confuse the enemy in combat. Stainless steel microwire is also an ideal material for making cut-resistant gloves.
Compared with organic and inorganic fibers, stainless steel microwires have higher elasticity and flexibility (the softness of stainless steel fiber microwires of 8μm is equivalent to that of 13μm hemp fiber), flexibility, and adhesion (when the surface is properly treated, Very good bonding with other materials, suitable for any kind of composite material), abrasion resistance, high temperature resistance (in an oxidizing environment, the temperature can be used continuously at 600 ℃), corrosion resistance (HNO3, alkali and organic solvent resistance) Corrosion), better air permeability, electrical conductivity, magnetic permeability, thermal conductivity, self-lubricating and sintering properties. At the same time, the unique environmental protection and reusability of stainless steel microwires have greatly improved their use value in social production and life.
The stainless steel microwire anti-radiation fabric utilizes the unique and stable electromagnetic shielding performance of the stainless steel microwire. There are currently four types of anti-radiation fabrics on the market: stainless steel microwire anti-radiation fabrics, multi-element (nano) anti-radiation fabrics, copper/nickel ion anti-radiation fabrics and silver fiber anti-radiation fabrics. Among them, the most popular and effective is the stainless steel microwire anti-radiation fabric.
The stainless steel microwire also has good antibacterial properties, and its antibacterial effect is obvious and long-lasting. Because of the extremely strong metal ions, the stainless steel microfilament textile fabric can release 5000-8000 negative ions per square centimeter. The medical field test proves that the stainless steel microfilament products can inhibit a variety of bacterial strains, and the antibacterial effect is satisfactory.
In addition to the above main uses, filter materials, conductive plastics, fiber reinforced materials, anti-counterfeiting materials, sound-absorbing materials, etc., made of stainless steel microwires as substrates, are also widely used in electronics, chemical, machinery, military, food, medicine and other industries. Development and utilization have opened up broad application prospects.
